Description
IC698PSA100 Product Overview
The IC698PSA100 is a 100 W plug-in power-supply module that occupies the left-most slot (slot 0) of every GE RX7i PACSystems rack. It auto-ranges from 85–264 VAC, 47–63 Hz or 100–150 VDC and delivers three isolated DC outputs (+5 V, +12 V, –12 V) required by the CPU, analog I/O, and communication cards.

In the automation hierarchy the unit sits at the “backplane power” layer: it provides logic-level sequencing signals (ACFAIL#, SYSRESET#) and up to 20 A on the +5 V rail while riding through at least one AC line cycle (15 ms) without loss of output—enough to keep the CPU alive during upstream breaker transfers. Electronic over-current, over-voltage, and over-temperature protection are standard; faults are signalled by front-panel LEDs and can be cleared by cycling the on-board logic switch or removing the overload.
Because the module is convection-cooled and certified for Zone 2 hazardous locations, it is widely used in turbine skids, compressor stations, and off-shore platforms where additional fans or external supplies are undesirable.

Core Features & Customer Value
Auto-ranging input – Accepts 85–264 VAC or 100–150 VDC without jumpers, so the same part number works worldwide and rides through plant battery float-voltage swings without nuisance shutdowns
Auto-ranging input – Accepts 85–264 VAC or 100–150 VDC without jumpers, so the same part number works worldwide and rides through plant battery float-voltage swings without nuisance shutdowns
.
Triple-rail in one slot – Delivers +5 V (20 A), +12 V (2 A), and –12 V (1 A) from a single module, eliminating separate DC/DC bricks and their associated wiring, fusing, and heat
.
15 ms ride-through – Holds all outputs valid for at least one AC line cycle, bridging upstream breaker transfers and keeping the CPU alive during voltage dips
.
Convection cooling – No fan required up to 60 °C, reducing maintenance and allowing installation in sealed turbine or off-shore skids where forced air is impractical
.
Zone 2 / marine certification – ATEX, ABS, BV, DNV-GL, and LR approvals allow direct installation in hazardous-location panels without additional isolation transformers
.
Typical Applications
In combined-cycle power plants the IC698PSA100 is routinely installed in the left-most slot of RX7i racks that govern gas-turbine fuel valves, inlet-guide-vane actuators, and cooling-water pumps. The 20 A +5 V rail powers the CPU and high-speed counter modules, while the ±12 V outputs feed analog I/O cards.

The 20 A +5 V rail powers the CPU and high-speed counter modules, while the ±12 V outputs feed analog I/O cards.
In pipeline compressor stations the same supply runs off 125 VDC battery, providing uninterrupted power to the anti-surge PLC and the ±12 V transmitter excitation even during AC outages.
Because the module is certified for marine environments, it is also used on off-shore platforms for well-head control panels without needing additional HVAC or fans.
